Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100580, here are decompositions:
- 31 + 100549 = 100580
- 43 + 100537 = 100580
- 61 + 100519 = 100580
- 79 + 100501 = 100580
- 97 + 100483 = 100580
- 163 + 100417 = 100580
- 223 + 100357 = 100580
- 283 + 100297 = 100580
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,580 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100580 first appears in π at position 417,870 of the decimal expansion (the 417,870ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
